Abstract: It is well established that test machine stiffness can influence the results in uni-axial compression tests on ice. This comes about because the conventional compression machines are not substantially stiffer than the piece of ice under test; hence the test becomes a complicated ice-structure interaction process. In this note, a simple model of this process is outlined and the defining equations are established. This yields a correction formula which accounts for the stiffness of the test machine. The model is checked for both columnar freshwater ice and granular sea ice by comparing the corrected strength values for three different test machines with those measured using a high-capacity closed-loop test machine.
